An initial design of a split flow liquid hydrogen turbopump for the Dual Expander Aerospike Nozzle (DEAN) upper stage engine was completed. The engine nozzle is an annular aerospike. The engine cycle requires a combustion chamber pressure of 1, psia. The DEAN is designed to deli lbf of thrust and seconds of : John R. Black, Michael A. Arguello. A liquid-propellant rocket engine is a rocket propulsion system that uses a liquid propellant, combining a liquid fuel (such as kerosene or liquid hydrogen) in a thrust chamber with a liquid oxidizer (such as liquid oxygen or fuming nitric acid). Very efficient and controllable, such .
hydrogen pump is a three-stage centrifugal pump while the high pressure liquid oxygen pump is a back- to-back single stage centrifugal pump with a single common volute. Unlike the SSME, the Ariane V has just one hydrogen and one oxygen pump as shown in Figure 1. Turbopump Rotor Dynamics Because of high power density and low damping in rocket turbopumps, these machines exhibit in their most extreme form a variety of vibration effects, which are either absent or masked by normal damping mechanisms in other turbo machines. The low damping is especially prominent in liquid hydrogen pumps, because of the.

The rotor of turbopump is directly supported by two sets of self-lubricated ball bearings in cryogenic pump fluid. The shaft seal of turbopump is installed between the cryogenic pump and the hot gas turbine.
The shaft seal system must seal the cryogenic propellants and the combustion gases (steam with rich hydrogen gas) safely and securely. The tribo characteristics of self-lubricating mm-bore ball bearings with a retainer of glass cloth-polytetrafluoroelhylene (PTFE) laminate, which has elliptical pockets with a large pocket clearance, were tested under thrust loads at speeds up to rpm, 2 million DN, in liquid hydrogen (LH 2) and in liquid nitrogen (LN 2).During testing, the bearing torque, outer-race temperature, and.
ALS liquid hydrogen turbopump: Advanced Development Program. By Nancy R. Shimp and George J. Claffy. Abstract. The point of departure (POD) turbopump concept was reviewed and finalized. The basis for the POD was the configuration presented in the Aerojet proposal.
After reviewing this proposal concept, several modifications were made. Authority-to-proceed (ATP) was given on 1 May APD was directed to close out the program on 6 August The objective of the program was to design and develop a highly reliable, low cost liquid hydrogen (LH2) turbopump for the ALS engine.

ASME Turbomachinery Technical Conference and Exposition, Seoul, South Korea, GT ALS Turbomachinery Technology Advanced Development Programs are being pursued by Rocketdyne, Aerojet, and Pratt & Whitney to define and validate design approaches toward producing low-cost, reliable liquid-hydrogen and liquid-oxygen turbopumps for a kN ( klb) thrust Advanced Launch System.
A coupled analysis of inlet guide vanes, inducer blades, and the following struts is carried out via a Computational Fluid Dynamics (CFD) method.
The complex 3-D components are part of a liquid hydrogen fuel turbopump for Advanced Expander Test Bed (AETB) engine. Numerical simulation is. turbopump, placed in series for each of the liquid hydrogen and liquid oxygen loops, generated high pressures across a wide range of power levels.
A weight target of 2, kg (6, pounds) and tight Orbiter ascent envelope requirements yielded a compact design capable of generating a nominal chamber pressure of kg/cm 2(3, pounds/in 2. A turbopump is a propellant pump with two main components: a rotodynamic pump and a driving gas turbine, usually both mounted on the same shaft, or sometimes geared purpose of a turbopump is to produce a high-pressure fluid for feeding a combustion chamber or other use.
There are two types of turbopumps: a centrifugal pump, where the pumping is done by throwing fluid .Liquid hydrogen and liquid oxygen turbopump conceptual designs were prepared and the designs were used to establish hydrostatic bearing size and performance requirements.
The turbopump designs included provision for operation when bearing supply pressure is insufficient to support the rotor.The idea of liquid rocket as understood in the modern context first appears in the book The Exploration of Cosmic Space by Means of Reaction Devices, by the Russian school teacher Konstantin seminal treatise on astronautics was published in Maybut was not distributed outside Russia until years later, and Russian scientists paid little attention to it.
